ChangeLog
src/main/java/org/monetdb/mcl/parser/StartOfHeaderParser.java
Branch: default
Log Message:
Implemented fix for released monetdb-jdbc-3.0.jre8.jar and
monetdb-mcl-1.19.jre8.jar when it is was run using java build 1.8.0_###.
It would throw: java.lang.NoSuchMethodError:
java.nio.CharBuffer.mark()Ljava/nio/CharBuffer;i
at org.monetdb.mcl.parser.StartOfHeaderParser.getNextAsString(Unknown Source)
at org.monetdb.jdbc.MonetConnection$ResponseList.executeQuery(Unknown Source)
at org.monetdb.jdbc.MonetConnection$ResponseList.processQuery(Unknown Source)
at org.monetdb.jdbc.MonetStatement.internalExecute(Unknown Source)
at org.monetdb.jdbc.MonetStatement.execute(Unknown Source)
The problem is caused by a change in java.nio.CharBuffer API (return types of
methods mark() and reset() have changed from Buffer to CharBuffer) from Java 8
to Java 9+.
